How Password Protection Works
Unlike traditional PDF password protection that encrypts the entire file, PdfWarden adds password gates to share links. This means you can create multiple links to the same document, each with different passwords for different recipients.
Why Link-Level Passwords Are Better
Traditional PDF encryption requires recipients to have compatible PDF readers and remember complex passwords. With PdfWarden, the PDF itself remains unchanged. Recipients simply enter a password in their browser before viewing.
Key Advantages
- No software required: Works in any modern web browser
- Easy password changes: Update passwords without touching the PDF
- Instant revocation: Disable a link immediately if compromised
- Multiple access levels: Different passwords for different stakeholders
Security Features
Passwords are hashed using bcrypt with a work factor of 12 before storage. Even if our database were compromised, passwords remain protected. We never store plaintext passwords or reversible hashes.
Perfect for Confidential Documents
Sales proposals, legal contracts, financial reports, and HR documents all benefit from password protection. You maintain control over who can access your content, even after you've sent the link.
Combine with Other Security Layers
Stack password protection with email verification, domain allowlists, and expiration dates for maximum security. Each share link can have independent security rules.
